Re: HP-71B Ram Modules Message #4 Posted by Karl Hafen on 15 July 1999, 1:22 a.m., in response to message #2 by DaveC I have a 64k module. It is made be CMT and plugs in the port where the card reader usually is.

Re: HP-71B Ram Modules Message #5 Posted by Ulf Hallmann on 13 July 1999, 3:03 p.m., in response to message #1 by jeff RAM modules up to 96k were available and were plugged into the card reader bay.

Re: HP-71B Ram Modules Message #6 Posted by Carlos Murillo on 14 July 1999, 11:31 p.m., in response to message #1 by jeff I have seen 32K and 64K modules by Corvallis MicroTechnology (CMT) and 96K, card-reader port RAM modules by Handheld Products. They are _very_ rare. It took two years before I could find someone who would sell me a 96K module. It is also possible to solder up to 4-5 standard form factor modules inside the HP71 (not recommended for the faint of heart), so that the front ports are left free for ROMS.
